摘要
随着我国直流输电工程的大量投运,我国电网发生大规模直流偏磁的几率也在增加。本文总结了国内外变压器直流偏磁研究现状,分析了当前研究存在的主要问题,从直流偏磁的产生机理研究、直流偏磁对交流电网的影响研究和直流偏磁治理原则及治理措施研究三个方面进行了关键技术分析,并分类提出了可进一步研究的重点内容。
With a large number of DC power transmission project put into operation in China,the occurrence probability of large-scale DC bias is also increasing.The current situation of the research on the DC bias of transformer in China and abroad is summarized in this paper,and the main problems in the current research are analyzed,including the generation mechanism of DC bias,the influence of DC bias on AC power grid and the principle of DC bias control and the control measures,and the key content of further research is put forward in Classification.
